Browning is one of the key factors that influenced the callus subculture of tree peony (Paeonia suffruticosa Andr.). Effects of medium composition and exogenous hormones: macro elements of Murashige and Skoog (MS salts) and iron salt (Fe2+), pH, agar and 6-benzylaminopurine (6-BA), 1-naphthaleneacetic acid (NAA) and kinetin (KT) on the callus browning of P. suffruticosa ‘Shan Hu Tai’ in vitro were studied in this paper. Results showed that the browning of P. suffruticosa callus were more sensitive to KT than 6-BA in different concentrations of 6-BA and KT separately with different concentrations of NAA, and reduced to the lowest (13.3%) under 0.5 mg·L-1 NAA plus 0.3 mg·L-1 KT. 1/4 × MS plus 1/4 × Fe2+ was the best basic medium in which the browning rate was only 18.2%. The browning rate of the callus was the lowest of 4.0% under pH 6.5 and the callus grew better in 7.0 g·L-1 agar than others. This study indicated that the best medium preventing P. suffruticosa callus in vitro from browning was: 1/4 × MS medium supplemented with 6.95 mg·L-1Fe2+, 0.3 mg·L-1 KT, 0.5 mg·L-1 NAA, 6.0 g·L-1 agar and 30 g·L-1 sucrose in pH 6.5.

There is a common phenomenon in China where the upstream and downstream hydropower stations of Cascade Hydropower Stations (CHS) belong to diferent operating entities. When independently participating in market bidding, upstream and downstream hydropower station information sharing blocked is likely to lead to the water fow mismatch of bidding volume, and resulting in no water can be used or water-abandond of downstream power plant. To make up bidding electricity shortfall of downstream station in day-ahead power market, a balance mechanism is proposed, in which downstream station through power contract transaction in the days or system punishment to balance electricity deviation. Power contract transaction includes centralized contract market and negotiated transaction with upstream station, system unbalancing penalty also as virtual transactions, then the problem is switched to electricity deviation optimal allocation in the trading portfolio. For price volatility of all transaction types, trading portfolio risk decision model of downstream power stations deviation electricity based CVaR framework is builded, which achieving minimum CVaR risk of downstream power plant electricity deviation as well as meetting preset expectation loss constraint. Finally, through the analysis of a CHS in southwestern China, it is shown that the model and method proposed in this paper can efectively reduce the imbalance between the winning electricity and incoming water matching of downstream power stations, and efectively improve the stability of hydropower consumption and power market operation

Objective: To assess the effects of perioperative comprehensive supportive care interventions on outcome of Chinese esophageal cancer patients in a prospective study. Methods: 60 patients with primary esophageal carcinoma were randomized into an intervention group (IG, n=31) and a control group (CG, n=29). The Chinese version of symptom checklist-90 (SCL-90) was adopted to assess their psychological status. The interventions, including health education, psychological support, stress management, coping strategies and behavior training, were carried out in 3 phases (preoperative, postoperative I and postoperative II), and psychological effects were thereafter evaluated accordingly before surgery, and 1 week, 4 weeks and 24 weeks post-surgery. Medical costs were estimated at discharge. Survival of patients was estimated each year post-surgery. General health status and satisfaction-with-hospital were surveyed by a follow-up questionnaire 4 years post-surgery. Results: All the subjects demonstrated higher scores in the preoperative phase than the normal range of Chinese population concerning 7 psychological domains including somatization, obsessive-compulsive, depression, anxiety, hostility, phobic anxiety and paranoid ideation. Although no significant difference was observed between the two groups at admission, the scores of IG, which tended to decrease at a faster rate, were generally lower than those of CG at weeks 1, 4 and 24 post-surgery. The length of hospital stay and medical costs of IG were significantly less than those of CG and satisfaction-with-hospital was better. However, there was no significant difference in 4-year survival or health status between two groups. Conclusions: Appropriate perioperative comprehensive supportive care interventions help to improve the psychological state of Chinese patients with esophageal carcinoma, to reduce health care costs and to promote satisfaction of patients and their families with hospital.

Zhu, Ping,Fu, Ju-Fang,Wang, Bo,Lin, Jing,Wang, Yan,Fang, Ning-Ning,Wang, Dan-Dan Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.10
Background: The aim of this study was to describe the characteristics of male spouse caregivers of breast cancer patients in China, assess their quality of life (QOL), and investigate the influencing factors. Materials and Methods: A total of 243 breast cancer patient-spouse caregiver dyads were recruited from four hospitals in Shanxi and Anhui province of China. A cross-sectional design was applied to collect data and the Chinese version of the Medical Outcomes Study 36-item Short Form (SF-36) was used to measure caregivers' QOL, and the Chinese version of M.D. Anderson Symptom Inventory (MDASI-C) was applied to measure patient symptom severity and interference. Pearson's correlation was used to examine the correlations between caregiver burden and QOL. The multiple regression analysis was used to determine the most predictive factors influencing QOL. Results: The scores of all SF-36 scales were above 50.0, which were much lower than that of general mainland Chinese males. Mental QOL was significantly worse than physical QOL. Spouses demographic characteristics, caregiving-related variables and patient symptoms were related to spouse QOL. Caregiver burden has a negative relationship with QOL. Conclusions: A decrease in life events and patient symptoms, as well as increase in spouse sleeping time and family income, ought to improve QOL.

Peptidomics analysis of enzymatic hydrolysis beef
Dan Qin,Liping Wang,Rui Fang,Ziteng Yu,Li Mo,Min Liu 한국식품과학회 2022 Food Science and Biotechnology Vol.31 No.10
In this study, we investigated the changes in the composition of peptides during the digestion of tenderized beef treated with commercial proteinase K, flavourzyme, and bromelain. The degree of hydrolysis (DH) values before and after simulating gastric digestion were highest with proteinase K treatment. In the proteinase K-treated sample, the highest number of missing peptides was identified after gastrointestinal digestion. Additionally, the maximum number of new peptides was identified during gastric digestion. The flavourzyme is the only exopeptidase among the three enzymes, and the sample treated with it could produce more unique peptides after gastrointestinal digestion. Enzymatic tenderization altered the peptide composition and bioactivity of beef proteins during gastrointestinal digestion. The number of peptides, as well as unique peptides in the protease-treated sample, were more than those in control through gastric digestion. In contrast, the opposite was observed post gastrointestinal digestion.

Background: Although flowers of Panax ginseng Meyer (FPG), Panax quinquefolius L. (FPQ), and Panax notoginseng Burk. (FPN) have been historically used as bothmedicine and food, each is used differently in practice. Methods: To investigate the connection between components and enhancing immunity activity of FPG, FPQ, and FPN, a method based on a rapid LC coupled with quadrupole time-of-flight MS and immunomodulatory activity study evaluated by a carbon clearance test were combined. Results: According to quantitative results, the ratio of the total content of protopanaxatiol-type ginsenosides to protopanaxadiol-type ginsenosides in FPN was 0, but ranged from 1.10 to 1.32 and from 0.23 to 0.35 in FPG and FPQ, respectively. The ratio of the total content of neutral ginsenosides to the corresponding malonyl-ginsenosides in FPN (5.52 1.33%) was higher than FPG (3.2 0.64%) and FPQ(2.39 0.57%). The colorimetric analysis showed the content of total ginsenosides in FPQ, FPG, and FPN to be 13.75 0.60%, 17.45 0.42%, and 12.45 1.77%, respectively. The carbon clearance assay indicated that the phagocytic activity of FPG and FPQ was higher than that of FPN. A clear discrimination among FPG, FPQ, and FPN was observed in the principal component analysis score plots. Seven compounds were confirmed to contribute strongly by loading plots, which may be the cause of differences in efficacy. Conclusion: This study provides basic information about the chemical and bioactive comparison of FPG, FPQ, and FPN, indicating that protopanaxtriol-type ginsenosides and malonyl-ginsenosides may play a key role in their enhancing immunity properties.

Sulfhydryl Cotton Enrichment Separation-Determination of Silver in Geological Samples by ICP-MS
Dan Li,Zhifei Zhao,Qin Chu,Jindong Fang 대한화학회 2011 Bulletin of the Korean Chemical Society Vol.32 No.10
A rapid and inexpensive method was developed for the determination of trace silver in geological samples by using sulfhydryl cotton coupled with ICP-MS. The interferences such as ^90Zr, ^92Mo and ^93Nb on silver were investigated in detail. Sulfhydryl cotton was found to be an effective adsorbent for separation of interferences for Ag in the solutions. Excellent agreements with the certified values were obtained for all the certified reference materials. The memory effects of Ag by ICP-MS were examined by using different agents, including water, nitric acid, and HCl-thiourea to all standards/samples. The agents also acted as cleansing solutions. A combination of HCl with thiourea gave the minimum memory effect. For comparison of results, a proposed Chinese Geology Survey procedure DC-ARC-AES and a direct determination pretreatment method of ICP-MS (water bath- auqa regia digestion) were studied. Under optimal conditions, the detection limits of our method for ^107Ag and ^109Ag were 1.2 ng/g and 1.3 ng/g, which offered much better accuracy for some difficult analysis geological samples such as GBW07604, GBW07605.
